PRIORITY CLAIM

This patent application is a continuation of, and claims priority to, U.S. patent application Ser. No. 12/962,940, filed on Dec. 8, 2010, and entitled “MOBILE BOTNET MITIGATION.” The entirety of the aforementioned application is hereby incorporated by reference herein.

TECHNICAL FIELD

The subject disclosure relates to mobile communications and, more particularly, to the mitigation of bot networks (botnets) in wireless communication systems and/or on mobile communication devices.

BACKGROUND

A wireless communication system can be utilized to provide wireless access to various communication services (e.g., voice, video, data, messaging, content broadcast, etc.) for users of the system. Wireless communication systems can operate according to a variety of network specifications and/or standards, such as Universal Mobile Telecommunications System (UMTS), Third Generation Partnership Project (3GPP) Long Term Evolution (LTE), High Speed Packet Access (HSPA). These specifications and/or standards use different modulation techniques, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Multi-Carrier CDMA (MC-CDMA), Single-Carrier CDMA (SC-CDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-Carrier Frequency Division Multiple Access (SC-FDMA), and so on.

Technological advances have provided significant increases in the computing power and networking capabilities of mobile devices. For instance, a number of smart phones and personal digital assistants (PDA) currently run full-fledged operating systems, employ powerful processors, and have broadband connectivity to the internet that rivals desktop computers and laptops. The technical capabilities of these devices have made them appealing to professionals, students, and casuals users alike. Resulting in a large user base that is non-technical in nature, and has little understanding of digital security threats. These aspects make the ever more powerful mobile devices an attractive target for cyber criminals.

In particular, botnets in mobile devices are a growing concern for mobile device users and wireless network administrators. Since these devices are ubiquitous and are expected to outnumber personal computers in the near future, they are high-value targets for cyber criminals intending to control, own and rent them for cyber criminal activities. A compromised mobile device under the control of a botnet can cause serious issues for both the user and the associated communication infrastructure. A bot program on a mobile device can transmit spam messages over the wireless network, make expensive international calls, or send text messages to premium numbers without the user's knowledge or permission. Accordingly, it would be desirable to implement techniques for effectively mitigating botnets in mobile devices and wireless communication systems.

Mitigation of mobile bot networks is presented herein. A botnet detection engine can analyze data traffic and data flows on a network, and employ a plurality of techniques to identify devices that are suspected of behaving as bots. The botnet detection engine can generate a traffic profile of the suspected bot behavior, and forward the traffic profile to the device that is suspected of behaving as a bot. Upon receipt of the traffic profile, the device can correlate data traffic on the device to the traffic profile in order to identify one or more applications on the device responsible for the suspected bot behavior. The device can remove the applications, or take other mitigating actions, such as selectively dropping data packets generated by the applications.

In accordance with one aspect, a method is provided for botnet mitigation in a wireless network that includes the steps of analyzing data traffic in the wireless network, detecting at least one device, operable on the wireless network, that is engaging in bot behavior, generating a profile for the bot behavior, and communicating the profile to the at least one device that is engaging in the bot behavior.

In accordance with another aspect, a system is provided that includes an analysis component configured to monitor data flows in a network, and identify at least one device exhibiting bot behavior, a profile generation component configured to produce a traffic profile of the bot behavior, and an alert component configured to send the traffic profile of the bot behavior to the at least one device exhibiting the bot behavior.

In accordance with yet another aspect, a communications device is provided that includes an information acquisition component configured to obtain at least one profile of bot behavior occurring on the communications device, a detection component configured to inspect data traffic on the communications device, and configured to compare the data traffic to the at least one profile of bot behavior, and a protection component configured to at least one of: erase at least one application from the communications device identified as generating the data traffic correlating to the at least one profile of bot behavior, or perform automatic mitigation including at least one of selectively dropping at least one data packet generated via the at least one application, quarantining the at least one application, or blocking user access to the at least one application.

To the accomplishment of the foregoing and related ends, the various embodiments, then, comprise the features hereinafter fully described. The following description and the annexed drawings set forth in detail certain illustrative aspects of the various embodiments. However, these aspects are indicative of but a few of the various ways in which the principles of the various embodiments may be employed. Other aspects, advantages and novel features of the various embodiments will become apparent from the following detailed description when considered in conjunction with the drawings.

FIG. 1 illustrates an example network 100 in accordance with various aspects described herein. The network 100 includes a core network 102, a mobility network 104, and a plurality of mobile devices 106. The core network 102 can have a plurality functions including, but not limited to, session management, and transport for data packets in the network 100. The core network 102 is also referred to as the backbone network, in part, because it connects the mobility network to the Internet. For example, the core network 102 can be comprised of a wired internet protocol (IP) network where both wired traffic and wireless or mobility traffic traversing the internet flows. Virtually all data transacted on the mobility network 104 (e.g., data flows, data traffic) will flow through the core network 102.

The mobility network 104 can have a plurality of functions including, but not limited to, enabling access to the network 100 by the mobile devices 106, allocating network resources (e.g., internet protocol addresses, etc.) to the mobile devices 106, handling traffic/signaling between the mobile devices 106 and the core network 102, providing mobility management, and so forth. Mobility management can include, but is not limited to, tracking the location of the mobile devices 106, and enabling: calling; text messaging (e.g., SMS); multimedia messaging (e.g., MMS); internet service and browsing; and other mobile services to be provided to the mobile devices 106. The mobility network 104 can include a plurality of base stations or access points (not shown) that enable the mobile devices 106 to communicate with a plurality of devices on the Internet, wherein the traffic is carried by the core network 102.

The mobile devices 106 can include, but are not limited to, tablet computers, smart phones, mobile phones, netbooks, portable music players, personal digital assistants (PDAs), laptops, electronic book devices, global positioning systems (GPS), and so forth. For example, FIG. 1 illustrates the network 100 containing a plurality of mobile devices, including a tablet computer 106A, a smart phone 106B, a mobile phone 106C, and a netbook 106 d connected to the mobility network 104. The mobile devices 106 can use the network 100 to access the internet, send/receive text messages, send/receive multimedia messages, execute voice calls, download applications, and so forth. The enhanced connectivity and technical capabilities of mobile devices 106 can leave them vulnerable to malicious software (malware), including malicious bots controlled by cyber criminals. For example, mobile devices 106 can receive a text messages that exploit one or more vulnerabilities in the operating system of the mobile devices 106 to install malware, access a website that installs malware on the mobile devices 106, access an electronic mail (email) link that installs malware on the mobile devices 106, or download a program/application that appears to be harmless (e.g., a video game), but is in fact malware. The malware can integrate compromised mobile devices 106 into a botnet, wherein the malware interacts with other compromised devices to form a small network, so that they can attack targets cooperatively (discussed below).

Turning now to FIG. 2, illustrated is an example botnet 200 in accordance with aspects described herein. The botnet 200 includes a plurality of compromised mobile devices 202. As discussed previously, the compromised mobile devices 202 can be infected with malware via a plurality of techniques, including but not limited to text/multimedia messages, email, websites, and/or applications. When the mobile devices 202 are compromised, the malware can integrate the compromised mobile devices 202 into the botnet 200. Each of the compromised mobile devices 202 can be controlled by a set of command and control servers 204. It is to be appreciated that the set of command and control servers 204 can be comprised of a single command and control server. Typically, the set of command and control servers 204 are operated by a user acting as a bot master. For example, the bot master can issue commands to the compromised mobile devices 202, via the set of command and control servers 204, to generate spam messages directed toward a set of remote targets 206. It can be desirable for a bot master to generate spam using a large number of compromised mobile devices 202, as opposed to a single source, in order to escape detection. As an additional example, the bot master can issue commands to the compromised mobile devices 202, via the set of command and control servers 204, to execute a denial of service (DoS) attack against the set of remote targets 206. During a DoS attack, essentially, the bot master will use the compromised mobile devices 202 to saturate the set of remote targets 206 (e.g., website, web server, etc.) with communication requests (e.g., pings).

Additionally or alternatively, the compromised mobile devices 202 can be arranged in a peer-to-peer bot network (P2P botnet). In the P2P botnet, there is not a command and control server 204; rather, each compromised mobile device 202 is both a server and a client. The bot master can inject commands at any point in the P2P botnet, and the commands are disseminated among the compromised mobile devices using a peer-to-peer (P2P) communication protocol. Based on the foregoing, it can be appreciated that it would be desirable for mobile device users and wireless network administrators to have a system and/or method for mitigating malware, such as botnets, from infecting mobile devices.

Referring to FIG. 3, illustrated is an example block diagram of a botnet mitigation system 300 in accordance with aspects described herein. The botnet mitigation system 300 includes a botnet detection component 302, a botnet mitigation component 304, and a bot defense component 306. The botnet detection component 302 operates, functions, or otherwise executes in the core network 102. Additionally or alternatively, the botnet detection component 302 can operate, function, or otherwise execute at an edge of the network 100, where the core network 102 connects to the mobility network 104. Placement of the botnet detection component 302 in the core network 102 or the edge of the network 100 enables the botnet detection component to analyze data flows and detect data flow patterns from virtually everywhere in the network 100 and/or mobility network 104.

The botnet detection component 302 can identify, recognize, or otherwise detect a set of devices, such as the mobile device 106 that are behaving like bots, and can also generate a traffic profile corresponding with the detected behavior. For example, typical bot behavior can include transmitting spam messages, scanning the network 100, and/or generating a set of traffic anomalies, wherein traffic anomalies consist at least in part of a set of data flows outside of or beyond the set data flows typically observed on the network 100. If the bot is an internet relay chat (IRC) bot, then the traffic profile of the bot can include sending traffic on a specific IRC port. Additionally or alternatively, the botnet detection component 302 can detect data flows from a bot on a compromised mobile device 106 to a known command and control server (See FIG. 2), and generate a traffic profile relating to communication with the known command and control server. Additionally or alternatively, the botnet detection component 302 can detect peer-to-peer botnets in the mobility network 104. The botnet detection component 302 can provide information relating to detected bots, including IP addresses, and traffic profiles, to the botnet mitigation component 304.

The botnet mitigation component 304 operates, functions, or otherwise executes in the mobility network 104. As discussed supra, the functionality of the mobility network 104 can include, but is not limited to, allocating network resources (e.g., IP address, IMSI, etc.) to the mobile device 106, handling traffic and signaling between the mobile device 106 and the core network 102, and so forth. The mobility network 104 can include a mobility component 308 that tracks mobility information, such as the IP address, physical location, and so forth of the mobile device 106. Where the network 100 is a second generation (2G) or a third generation (3G) network, the mobility component 308 can include a serving GPRS support node (SGSN) 310 and a gateway GPRS support node (GGSN) 312. The responsibilities of the SGSN 310 can include, but are not limited to, delivery of data packets to and from mobile devices within its geographical service area, packet routing and transfer, and authentication and charging functions. The GGSN 312 can be responsible for maintaining current location information for the mobile device 106, and maintaining routing data necessary to tunnel data to the SGSN 310 that services the particular mobile device 106. It is to be appreciated, that the aspects described herein are not limited to 2G or 3G networks, but can also be employed on various other communications networks, including, but not limited to, fourth generation (4G) wireless communication networks, such as those complying with the long term evolution (LTE) standards.

The botnet mitigation component 304 obtains, receives, or otherwise acquires information relating to detected bots from the botnet detection component 302, including, but not limited to, IP addresses, or traffic profiles. The botnet mitigation component 304 can use the information from the botnet detection component 302 to identify the compromised mobile device 106, and transmit, send, or otherwise communicate a warning message to the bot defense component 306 on the mobile device 106. The warning message can include, but is not limited to, the traffic profile of the bot infecting the mobile device 106, and/or a flag indicating that the mobile device (106) has been compromised by potential malware. The botnet mitigation component 304 can locate and communicate with the mobile device 106 via the mobility component 308.

The bot defense component 306 operates, functions, or otherwise executes in kernel space of the mobile device 106. The bot defense component 306 can correlate the flow of data in the kernel space of the mobile device 106 to the traffic profile included in the warning message in order to identify, locate, or otherwise determine an application or binary 314 that is generating the information contained in the traffic profile. The bot defense component 306 is able to inspect or intercept all data traffic on the mobile device 106 generated by applications and/or binaries, because it executes in the kernel space of the mobile device 106. When the bot defense component 306 has identified the application or binary related to the traffic profile the bot defense component 306 can remove, delete, or otherwise the erase the application or binary from the device. Additionally or alternatively, the bot defense component 306 can prompt a user to inform them that the binary or application is behaving as a bot, and allow the user to determine to remove, delete, or otherwise the erase the application or binary from the device. If the user determines not to remove the binary or application behaving as a bot, the bot defense component 306 can perform additional mitigating actions including, but not limited to, selectively dropping packets originating from the binary or application behaving as a bot. It is to be appreciated that a plurality of applications and/or binaries may correlate to the traffic profile obtained by the bot defense component 306. For instance, a user may have downloaded a plurality of games from the same publisher, wherein each game is infected with the same bot. It is to be appreciated that the bot defense component 306 can additionally or alternatively operate on a wired device (not shown), wherein the bot defense component 306 operable on a wired device can obtain the warning message from the botnet detection component 302 or the botnet mitigation component 304.

Turning now to FIG. 4, illustrated is an example block diagram of a botnet detection component 302 in accordance with aspects described herein. The botnet detection component 302 includes an analysis component 402, a profile generation component 404, and an alert component 406. The analysis component 402 analyzes data in the core network 102 or at the edge of the network 100 where the core network 102 connects to the mobility network 104 (see FIG. 1), and based on the analysis of data traffic and data flows can identify a set of ip addresses that are suspected of being compromised by malware and behaving as bots. In addition, the analysis component can determine if the suspect ip addresses are part of the mobility network 104 (See FIG. 1).

The analysis component 402 can detect the existence of bots in the network 100 via a plurality of techniques. For instance, the analysis component 402 can start with information related to one or more bots previously known to be in the network 100, and can identify data traffic and data flows that are similar to the data traffic and data flows generated by the known bots. In addition, the analysis component 402 can follow data traffic to a known command and control server (See FIG. 2), and identify bots that attempt to communicate with the known command and control server. Additionally, the analysis component 402 can employ cluster analysis and single out groups of IP addresses that behave in a similar manner that might be indicative of a botnet, such as scanning the network 100, sending spam messages, etc. Furthermore, the analysis component can detect peer-to-peer botnets in the network 100.

The profile generation component 404 generates a traffic profile of the suspected bot behavior. For example the profile generation component 404 can generate a profile for a suspected IRC bot that includes transmission of data on a set of IRC ports. The alert component 406 acquires, receives, or otherwise obtains the identity of the mobile devices 106 suspected of behaving as bots from the analysis component 402, and an associated traffic profile of the suspected bot behavior from the profile generation component 406. The identity and associated traffic profile of a suspected compromised mobile device are sent, transmitted, or otherwise provided to the botnet mitigation component (discussed below) by the alert component 406.

Referring to FIG. 5, illustrated is an example block diagram of a botnet mitigation component 304 in accordance with aspects described herein. The botnet mitigation component 304 includes an alert acquisition component 502, a device location component 504, and a communication component 506. The alert acquisition component 502 acquires, receives, or otherwise obtains an identity of a mobile device 106 that is suspected of behaving as a bot, and a traffic profile of the suspected bot behavior from the alert component 406 included in the botnet detection component 302 (See FIG. 4).

As discussed supra, the botnet mitigation component 304 operates, functions, or otherwise executes in the mobility network 104 (See FIG. 1). The functionality of the mobility network 104 can include, but is not limited to, allocating network resources (e.g., IP address, IMSI, etc.) to mobile devices, handling traffic and signaling between mobile devices and the core network 102, and so forth. The mobility network 104 can include a mobility component 308 that tracks mobility information, such as the IP address, physical location, and so forth of mobile devices operable on the network 100. The device location component 504 can determine a physical location of the suspected mobile device via the mobility component 308. In addition, the communication component 506 can send, transmit, or otherwise provide the suspected mobile device with the traffic profile of suspected bot behavior obtained from the botnet detection component 302. In addition, the communication component 506 can provide a flag or bit to the suspect mobile device to alert the mobile device that it may be infected with malware and/or be behaving as a bot.

FIG. 6 illustrates an example block diagram of a mobile device 106 in accordance with aspects described herein. As discussed supra, the mobile device 106 can include, but is not limited to, tablet computers, smart phones, mobile phones, netbooks, portable music players, personal digital assistants (PDAs), laptops, electronic book devices (e-book readers), global positioning systems (GPS), and so forth. Typically, the operating resources of mobile devices 106 can be broadly separated into kernel space 600 and user space 602. The kernel space 600 operates as a bridge between a set of applications 612-616 that execute, perform, or otherwise operate in the user space 602 and data processing performed by the hardware (not shown) of the mobile device 106. As a consequence, virtually all data traffic on the mobile device 106 can be observed from the kernel space 600. Therefore, it may be desirable for the bot defense component 306 to reside, operate, or otherwise execute in the kernel space 600 of the mobile device 106.

The bot defense component 306 includes an information acquisition component 604, a detection component 606, a user prompt component 608, and a protection component 610. The information acquisition component 604 acquires, receives, or otherwise obtains a traffic profile of suspected malware that may be causing the mobile device 106 to behave as a bot. In addition, the information acquisition component can obtain a flag or bit that serves to notify the bot defense component 306 that the mobile device 106 is suspected of behaving as a bot or infected with malware. It is to be appreciated that the flag or bit can be included or associated with the traffic profile. The detection component 606 can intercept, observe, or otherwise inspect virtually all data traffic generated on the mobile device 106, and can correlate the data traffic with the traffic profile to determine at least one application or binary responsible for generating the suspect traffic profile. Returning to an earlier example, the traffic profile for an IRC bot can include generating traffic on a particular set of IRC ports. The detection component 606 can observe virtually all the data traffic on the mobile device and determine which of the applications and binaries 612-616 is generating traffic on the particular set of IRC ports. For instance, the detection component 606 can determine that the bot binary 612 is generating the traffic on the particular IRC ports, and determine that bot binary 612 is malware.

The user prompt component 608 can inform the user via an onscreen display, or other appropriate means, that the malware has been detected on the phone, and for example, that the infected application, bot binary 612, is behaving as a bot. The user prompt 608 can prompt the user to remove the infected application or ignore the warning. If the user decides to remove the infected application then the protection component 610 deletes, erases, or otherwise removes the infected application from the mobile device 106. The protection component 610 can perform additional mitigating actions if the user decides to ignore the warning, including but not limited to automatically dropping packets from the suspected application, quarantining the suspected application, or blocking user access to the suspected application. A decision to perform such additional mitigating actions can be based at least in part on a determination that the additional mitigating actions are required to protect the user and/or the wireless networks from aggressive botnet attacks. Additionally or alternatively, the protection component 610 can delete, erase, or otherwise remove the suspected application or binary without prompting the user. For example, a default option or a predetermined preference may instruct the bot defense component 306 to automatically remove any suspected applications or binaries. It is to be appreciated that the mobile device 106, can include a virtually infinite number of applications, and a plurality of the applications may be acting as bots.

Turning now to FIG. 7, illustrated is an example user prompt for the botnet mitigation system in accordance with aspects described herein. A mobile device 702 is shown as a touch screen device, such as a tablet pc, smart phone, etc. However, as discussed previously, the mobile device can include, but is not limited to, mobile phones, net books, portable music players, personal digital assistants (PDAs), laptops, electronic book devices (e-readers), global positioning systems (GPS), and so forth.

As discussed supra, the mobile device 702 will receive, obtain, or otherwise acquire information regarding a traffic profile of an application or binary that is suspected of behaving as a bot and infecting the mobile device. A botnet defense component (See FIG. 6) can correlate the traffic profile to the data traffic on the mobile device 702, and determine the specific application or binary responsible for generating the suspected traffic profile. Once the responsible application has been determined, a message 704 can be displayed to the user that malware has been detected on the device, and the user can be prompted to delete the application (app) or binary 706 or ignore 708 the warning.

The user can choose either the delete app option 706 or ignore option 708, by a plurality of means including, but not limited to, touching, clicking, orally commanding, or otherwise selecting the appropriate choice. If the user selects the delete app option 706, then the botnet defense component will erase, remove, or otherwise delete the suspected application from the mobile device 702. Conversely, if the user selects the ignore option 708, then the suspected application may remain on the mobile device 702, or the botnet defense component can perform additional mitigating actions, including but not limited to automatically dropping packets from the suspected application, quarantining the suspected application, or blocking user access to the suspected application. A decision to perform such additional mitigating actions can be based at least in part on a determination that the additional mitigating actions would be beneficial to protect the user and/or the wireless networks from aggressive botnet attacks. It is to be appreciated that the foregoing is merely an example illustration set forth for simplicity of explanation, and those reasonably skilled in the art will be able to identify a plurality of user prompts that are within the scope of the subject disclosure.

In view of the example systems described supra, methods that may be implemented in accordance with the disclosed subject matter may be better appreciated with reference to the flow charts of FIG. 8-11. While for purposes of simplicity of explanation, the methods are shown and described as a series of blocks, it is to be understood and appreciated that the claimed subject matter is not limited by the order of the blocks, as some blocks may occur in different orders and/or concurrently with other blocks from what is depicted and described herein. Moreover, not all illustrated blocks may be required to implement the methods described hereinafter.

Turning now to FIG. 8, an example methodology for botnet mitigation in wireless networks is illustrated in accordance with aspects described herein. Methodology 800 can begin at block 802, wherein data flows and data flow patterns throughout a network are analyzed. At 804, a determination is made whether a device suspected of behaving as a bot has been detected in the network based on the analysis of the data flows and data flow patterns. If a device suspected of behaving as a bot has not been detected then the methodology returns to 802. If a device suspected of behaving as a bot has been detected, then at 806 a traffic profile of the bot behavior is generated. For example, typical bot behavior can include transmitting spam messages, scanning the network, and/or generating traffic anomalies. At 808, the physical location of the compromised device is determined, and at 810 the traffic profile of the suspected bot behavior is sent, transmitted, or otherwise provided to the suspected device.

At 812, the traffic profile is correlated with data traffic on the suspected device, and at 814 the application/binary responsible for generating the suspect traffic profile is identified based on the correlation of the data traffic with the traffic profile at 812. For example, if the bot is an IRC bot, then the traffic profile of the bot can include sending traffic on a specific IRC port, and it can be determined which application/binary is sending traffic on the specific IRC port.

At 816, a prompt can be displayed to the user informing the user that an application/binary on the device is behaving as a bot. The prompt can include options to delete the application/binary or ignore the warning. At 818, a determination is made whether the user has elected to delete the suspect application. If the user elects to ignore the warning or not delete the suspect application/binary (N at 818), then at 820 a determination is made whether additional action should be taken, the determination can be based at least in part on a decision that additional action is required to protect the user and/or the wireless networks from aggressive botnet attacks. If it is determined that additional action is not required (N at 820), then the methodology 800 can return to 802. If it is determined that additional action is required (Y at 820), then at 822 additional mitigation actions can be performed, including but not limited to automatically dropping packets from the suspect application/binary, quarantining the suspect application/binary, or blocking user access to the suspect application/binary. If the user elects to delete the suspect application/binary (Y at 818), then at 820 the application/binary is removed from the device.

Referring to FIG. 9, an example methodology for botnet detection in accordance is illustrated in accordance with various aspects described herein. Methodology 900 can begin at block 902, wherein the data flows and data traffic for a network are observed from the core network or an edge of the network where the core network and a mobility network are communicatively coupled. At 904, the observed data flows and data traffic are analyzed to determine if there are IP addresses in the network behaving as bots. A plurality of techniques can be employed to determine if there are mobile devices behaving as bots. For instance, the analysis can be based on one or more known bots in the network, and can identify data traffic and data flows that are similar to the data traffic and data flows generated by the known bots. Additionally or alternatively, analysis can include following data traffic to a known command and control server (See FIG. 2), and identifying bots that attempt to communicate with the known command and control server. Additionally or alternatively, analysis can include employing cluster analysis, and singling out groups of IP addresses that behave in a similar manner that might be indicative of a bot. Such behavior can include scanning the network, sending out spam messages, and so forth.

At 906, a determination is made whether an IP address suspected of behaving as a bot has been detected. If an IP address suspected of behaving as bot has not been detected (N at 906), then the methodology 900 can return to 902. If an IP address suspected of behaving as bot has been detected (Y at 906), then at 908 the suspect IP address is identified. At 910, a traffic profile of the suspected bot behavior can be generated. For example, if suspected bot behavior is of an IRC bot, then the traffic profile can include transmitting data on a particular set of IRC ports. As additional or alternative examples, the traffic profile can include generating spam messages, scanning the network, or virtually any malicious activity. At 912, the traffic profile and identity of the suspect IP address are communicated to the mobility network.

Turning now to FIG. 10, an example methodology of botnet mitigation is illustrated in accordance with various aspects described herein. Methodology 1000 can begin at block 1002, wherein a traffic profile and identity of a mobile device that is suspected of behaving as a bot is received, acquired, or otherwise obtained. As discussed supra, the identity of the suspect mobile device can include the IP address of the mobile device.

At 1004, a physical location of the mobile device can be determined via the mobility network. As discussed supra, the functionality of the mobility network can include, but is not limited to, allocating network resources to mobile devices, handling traffic and signaling between the mobile devices and the core network, and so forth. In addition, if the wireless network is a 2G or a 3G network, it can include a serving GPRS support node (SGSN) and a gateway GPRS support node (GGSN). The responsibilities of the SGSN can include, but are not limited to, delivery of data packets to and from wireless devices within its geographical service area, packet routing and transfer, and authentication and charging functions. The GGSN 312 can be responsible for maintaining current location information for the wireless device, and maintaining routing data necessary to tunnel data to the SGSN 310 that services the particular wireless device. Therefore, it can be appreciated how the determining the physical location of the suspect mobile device is accomplished via the mobility network.

At 1006, the traffic profile is communicated to the mobile device via the mobility network. As discussed supra, if the suspected bot behavior is of an IRC bot, then the traffic profile can include transmitting data on a particular set of IRC ports. As additional or alternative examples, the traffic profile can include generating spam messages, scanning the network, or virtually any malicious activity. Additionally, a warning flag or bit indicating that an application or binary that is acting as a bot is present on the mobile device can be communicated to the mobile device.

Turning now to FIG. 11, an example methodology of botnet mitigation on a mobile device is illustrated in accordance with aspects described herein. Methodology 1100 can begin at block 1102, wherein a suspected traffic profile is obtained, received, or otherwise acquired from a mobility network. The suspected traffic profile can include information relating to bot like behavior that is suspected of occurring on the mobile device. In addition, a flag or bit indicating that the mobile device may be infected by malware and/or behaving as a bot can be associated with the traffic profile.

At 1104, the data traffic on the mobile device is inspected, and at 1006 the data traffic on the mobile device is correlated, compared, or otherwise analyzed against the suspected traffic profile. For example, if the suspected traffic profile is of an IRC bot, then the traffic profile can be compared with the data traffic on the mobile device to determine if any applications or binaries are generating traffic on a suspected set of IRC ports.

At 1108, a determination is made as to whether a binary (or application) matching the traffic profile has been identified? If a binary matching the traffic profile has not been identified (N at 1108), then the methodology 1100 returns to the 1104, and continues inspecting data traffic on the mobile device. If a binary matching the traffic profile has been identified (Y at 1108), then at 1110 a determination is made whether to prompt the user. The determination of whether to prompt the user can be a default setting or predetermined preference, wherein the methodology always, never, or on the occurrence of a predetermined condition prompts the user to remove the bot. If the determination is made to prompt the user (Y at 1112), then at 1112 the user is prompted via an onscreen display, or other appropriate means, that malware has been detected on the phone, and that the determined binary is behaving as a bot. At 1114, a determination is made by the user whether to delete the suspected bot binary. If the determination is not to delete the suspected bot binary (N at 1114), then at 1116 a determination is made whether automatic mitigation should be performed, the determination for automatic mitigation can be based at least in part on a decision that mitigation action is required to protect the user and/or the wireless networks from aggressive botnet attacks. For example, the traffic profile obtained by the mobile device can include a warning or specification that additional action may be required to protect the user and/or wireless networks if the user elects not to remove the suspect binary. If it is determined that automatic mitigation is not required (N at 1116), then the methodology 1100 can terminate. If it is determined that automatic mitigation actions should be performed (Y at 1116), then at 1118 automatic mitigation actions can be performed, including but not limited to automatically dropping packets from the suspect binary, quarantining the suspect binary, or blocking user access to the suspect binary.

If the determination is made to delete the suspected bot binary (Y at 1114), then at 1120 the suspected binary is erased, deleted, or otherwise removed from the mobile device. Returning to 1112, if it is determined to not prompt the user (N at 1112) then the methodology proceeds to 1120, wherein the suspected binary is erased, deleted, or otherwise removed from the mobile device.

FIG. 12 illustrates a system 1200 that employs a decision component 1202 which facilitates automating one or more features in accordance with aspects described herein. Various embodiments (e.g., in connection with inferring) can employ various decision facilitating schemes for carrying out various aspects thereof. For example, a process for botnet detection, data flow and data traffic analysis, or profile generation can be facilitated via an automatic classifier system and process.

As used herein, the term “inference” refers generally to the process of reasoning about or inferring states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources. Furthermore, inference can be based upon logical models or rules, whereby relationships between components or data are determined by an analysis of the data and drawing conclusions there from. For instance, by observing that one user interacts with a subset of other users over a network, it may be determined or inferred that this subset of users belongs to a desired social network of interest for the one user as opposed to a plurality of other users who are never or rarely interacted with.

FIG. 13 illustrates an additional or alternative example aspect of a wireless system that can implement features and aspects described herein and operated in accordance with such features and aspects. The example system 1300 can include a modem 1302 that can wirelessly communicate with a wide area network, for example, employing a 2G/3G/3.5G/4G wireless connection. As an example, the modem 1302 can be a wireless wide area network (WWAN) modem/transceiver such as a GPRS/EDGE/CDMA/UMTS/HSPA/LTE modem that can transfer digital images (or other media files) and/or control data. Moreover, the modem 1302 can operate in any of the commonly used wireless spectrum bands. As an example, the modem 1302 can be IPv6 (Internet Protocol version 6) enabled. It can be appreciated that the modem 1302 can be embedded in the system 1300 or external to the system and can be connected to an antenna 1304 to receive and/or transmit data. The antenna 1304 can be external or internal. Moreover, the modem 1302 can receive instructions sent by a remote user (e.g. system subscriber) over a network, e.g., a mobile network platform that serves a network of deployed access points, to change one or more settings and/or perform one or more functions on the example system 1300, for example, load, delete or play a file.

Furthermore, the modem 1302 can also be configured to receive wireless alerts (SMS, Image)/broadcast from a mobile network platform. Additionally, the example system 1300 of a can include a SIM (Subscriber Identity Module) or USIM (Universal Subscriber Identity Module) 1306 associated with the system users account subscription. The SIM or USIM 1306 can be prepaid, flat rate monthly, or usage based. Further, the SIM or USIM 1306 may need to be a locked to the specific type of device (e.g., a wireless digital media that employs a WWAN modem) to prevent it from being used in a mobile phone or wireless data device to prevent network abuse if lower rates, including flat rate, are offered to the system subscribers.

A media receiving component 1308 can receive media files, e.g., content(s), sent to the example system 1300 through an access point via the modem 1302. Received media files can be displayed through display component 1310. The modem 1302 can include control functions to enable communication with the WWAN and transfer of data in the downlink. The modem 1302 can be downlink enabled and can optionally allow the ability to transfer data in the uplink (UL) direction beyond control channels. For example, the system 1300 can transfer data associated with available free space in memory 1312 to a mobile network platform in the UL. Further, the modem 1302 can be configured to allow network control such that transfer of data could occur at various times of the day based on network/sector loading due to traffic and propagation conditions and/or based on user preferences. Further, the modem 1302 can be configured to work on a prepaid condition or active account or unlimited usage account.

The system 1300 can typically include a processor 1314 that can be a processor based controller chip. Specifically, the processor 1314 can be a processor dedicated to analyzing information received by modem 1302 and/or generating information for transmission on the UL, a processor that controls one or more components of the system 1300, a processor that facilitates output of media files on a display screen 1316 or via speaker 1318, and/or a processor that both analyzes information received by modem 1302, generates information for transmission on the UL, controls one or more components of the system 1300 and facilitates output of media files on a display screen 1316 or via speaker 1318.

The system 1300 can additionally comprise memory 1312 that is operatively coupled to processor 1314 and that can store data to be transmitted, received data, data associated with analyzed signal and/or interference strength, information related to an assigned channel, power, rate, or the like, and any other suitable information for estimating a channel and communicating via the channel. Memory 1312 can additionally store media files received from a sender over a network. Further, memory 1312 can also store user preferences and/or predefined user settings. In one example, memory 1312 can be partitioned, such that locally downloaded media files (e.g. downloaded by an end user) are stored in one partition and remotely downloaded media files (e.g., content(s) are stored in another partition. A number of program modules can be stored in the memory 1312, including an operating system, one or more application programs, other program modules and/or program data. It is appreciated that the aspects described herein can be implemented with various commercially available operating systems or combinations of operating systems.

Additionally, a system bus (not shown) can be employed to couple system components including, but not limited to, the system memory 1312 to the processor 1314. The system bus can be any of several types of bus structure that may further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures.

The media files received from the mobile wireless network can be displayed on the display screen 1316 and/or audio files can be played via the speaker 1318. It can be appreciated that the media files stored in the memory 1312 can also be received via ports such as, but not limited to, USB, USB2, 1395, SD card, Compact Flash, etc. Additionally, system 1300 can include a power supply/battery 1320 that can be employed to power the system. As an example, power management techniques can be employed to save battery power, such that the battery can last longer between recharge cycles.

An end user can enter commands and information through one or more wired/wireless input devices, e.g., a keyboard, a pointing device, such as a mouse and/or a touch screen display 1316. A microphone 1322 can also be employed to enter data. For example, the end user can employ the microphone 1322 to enter an audio clip associated with an image. These and other input devices are often connected to the processor 1314 through an input device interface (not shown) that is coupled to a system bus, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a USB port, an IR interface, and so forth.

The system 1300 can further include a codec 1324 that can be employed encode and/or decode digital data. The codec 1324 can employ most any compression and/or decompression algorithm to compress/decompress a received media file. Furthermore, the system 1300 can include a GPS (global positioning system) 1326 that can be employed to determine the current geographical coordinates of the example the system 1300. The GPS 1326 can include a separate GPS antenna (not shown) or employ the antenna 1304 to communicate with a GPS satellite. In one example, the example system 1300 can receive broadcast warnings, emergency alerts, weather alerts, etc. based on the current coordinates.

In addition, the example system 1300 is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag, and telephone. This includes at least Wi-Fi and Bluetooth™ wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.

Wi-Fi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. Wi-Fi is a wireless technology that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11a) or 54 Mbps (802.11b) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices.

FIG. 16 illustrates a block diagram 1600 of a mobile network platform 1610 which can provide a botnet mitigation in accordance with aspects described herein. Generally, mobile network platform 1610 can include components, e.g., nodes, gateways, interfaces, servers, or platforms, that facilitate both packet-switched (PS) (e.g., internet protocol (IP), frame relay, asynchronous transfer mode (ATM)) and circuit-switched (CS) traffic (e.g., voice and data) and control generation for networked wireless communication. In an aspect, as described above, component within PS domain of network platform 1610 can be employed to effect communication in accordance with aspects described herein.

With respect to CS communication, mobile network platform 1610 includes CS gateway node(s) 1612 which can interface CS traffic received from legacy networks such as telephony network(s) 1614 (e.g., public switched telephone network (PSTN), or public land mobile network (PLMN)) or a SS7 network 1616. Circuit switched gateway node(s) 1612 can authorize and authenticate traffic (e.g., voice) arising from such networks. Additionally, CS gateway node(s) 1612 can access mobility, or roaming, data generated through SS7 network 1616; for instance, mobility data stored in a visitation location register (VLR), which can reside in memory 1620. Moreover, CS gateway node(s) 1612 interfaces CS-based traffic and signaling and gateway node(s) 1622. As an example, in a 3GPP UMTS network, CS gateway node(s) 1612 can be embodied, at least in part, in gateway GPRS support node(s) (GGSN).

In addition to receiving and processing CS-switched traffic (e.g., content(s) that can be part of a content(s) transmitted by a service provider) and signaling, PS gateway node(s) 1622 can authorize and authenticate PS-based data sessions with served mobile devices, non-mobile devices, and access points. Data sessions can include traffic, or content(s), exchange with networks external to the mobile network platform 1610, such as wide area network(s) (WANs) 1630 or service network(s) 1640; it should be appreciated that local area network(s) (LANs) 1650 can also be interfaced with mobile network platform 1610 through PS gateway node(s) 1622. Packet-switched gateway node(s) 1622 generates packet data contexts when a data session is established. To that end, in an aspect, PS gateway node(s) 1622 can include a tunnel interface (e.g., tunnel termination gateway (TTG) in 3GPP UMTS network(s) (not shown)) which can facilitate packetized communication with disparate wireless network(s), such as network platform and associated radio access network, Wi-Fi networks. It should be further appreciated that the packetized communication can include multiple flows that can be generated through service (e.g., provisioning) and application server(s) 1660. It is to be noted that in 3GPP UMTS network(s), PS gateway node(s) 1622 (e.g., GGSN) and tunnel interface (e.g., TTG) comprise a packet data gateway (PDG).

The mobile network platform 1610 also includes serving node(s) 1670 that convey the various packetized flows of data streams (e.g., content(s) or signaling directed to a subscribed data), received through PS gateway node(s) 1622. As an example, in a 3GPP UMTS network, serving node(s) 1670 can be embodied in serving GPRS support node(s) (SGSN).

Server(s) 1660 in mobile network platform 1610 can execute numerous applications (e.g., location services, online gaming, wireless banking, wireless device management . . . ) that can generate multiple disparate packetized data streams or flows, and manage (e.g., schedule, queue, format . . . ) such flows. Such application(s), for example can include add-on features to standard services provided by mobile network platform 1610. Data streams (e.g., content(s) or signaling directed to a file) can be conveyed to PS gateway node(s) 1622 for authorization/authentication and initiation of a data session, and to serving node(s) 1670 for communication thereafter.

Server(s) 1660 can also effect security (e.g., implement one or more firewalls) of mobile network platform 1610 to ensure network's operation and data integrity in addition to authorization and authentication procedures that CS gateway node(s) 1612 and PS gateway node(s) 1622 can enact. Moreover, server(s) 1660 can provision services from external network(s), e.g., WAN 1630, or Global Positioning System (GPS) network(s) (not shown). It is to be noted that server(s) 1660 can include one or more processors configured to confer at least in part the functionality of macro network platform 1610. To that end, the one or more processor can execute code instructions stored in memory 1620, for example.

Furthermore, the claimed subject matter can be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques to produce software, firmware, hardware, or any combination thereof to control a computer to implement the disclosed subject matter.
